It has been proposed by scientists that the evolutionary reason for the female body shape is due in part to this sexual selection.Sex-typical body shapes (a man's muscular physique and a woman's hourglass figure) are an outcome of evolutionary adaptation for reproductive fitness because they convey information about gene quality, health and fertility, which are important elements for mate ...
This body of water between England and France is 32 km wide, with a temperature of 15 to 18 degrees, strong currents, and jellyfish. [37] Due to the heavy tides, Kayadelen swam a total distance of 57 km in 15 hours and 8 minutes in 16-degree water.
At 21:40, [8] she was connected to a cardiopulmonary bypass machine that warmed up her blood outside of her body [16] [23] before it was reinserted into her veins. [14] Bågenholm's first heart beat was recorded at 22:15, [ 1 ] and her body temperature had risen to 36.4 °C (97.5 °F) at 0:49. [ 25 ]

In some cases measured arterial oxygen saturation values showed considerable arterial deoxygenation, with an extreme value of 25%. Heart rate changes similar to diving mammals in magnitude, and patterns of change were recorded, and changes in cardiac waveform at heart rates less than 40 beats per minute were linked to changes suggesting ...
The researchers suggest some of these changes could be tied to lifestyle or behaviour factors that cluster at these age groups. People go through ‘dramatic’ changes in their 40s and 60s ...
